AMD Goes Virtual With Liquid VR
AMD Liquid VR is not a retail product – it is an initiative to develop and deliver the best Virtual Reality (VR) experience in the industry.
AMD Liquid VR was announced at the Game Developers Conference in San Francisco, and the company describes it is a “set of innovative technologies focused on enabling exceptional VR content development” for hardware based on AMD silicon.
Developers will soon get access to the LiquidVR SDK, which will help them address numerous issues associated with VR development.
Platform and software rather than hardware
If you were expecting to see a sexy AMD VR headset with a killer spec, the announcement may be disappointing. However, if you are a “what’s under the bonnet” kind of geek, there are a few interesting highlights.
AMD has put a lot of effort into minimising motion-to-photon latency, which should not only help improve the experience, but also keep you from experiencing motion sickness, or hurling over that new carpet that really ties the room together.
Headline features of LiquidVR SDK 1.0 include:
Async Shaders for smooth head-tracking enabling Hardware-Accelerated Time Warp, a technology that uses updated information on a user’s head position after a frame has been rendered and then warps the image to reflect the new viewpoint just before sending it to a VR headset, effectively minimizing latency between when a user turns their head and what appears on screen.
Affinity Multi-GPU for scalable rendering, a technology that allows multiple GPUs to work together to improve frame rates in VR applications by allowing them to assign work to run on specific GPUs. Each GPU renders the viewpoint from one eye, and then composites the outputs into a single stereo 3D image. With this technology, multi-GPU configurations become ideal for high performance VR rendering, delivering high frame rates for a smoother experience.
Latest data latch for smooth head-tracking, a programming mechanism that helps get head tracking data from the head-mounted display to the GPU as quickly as possible by binding data as close to real-time as possible, practically eliminating any API overhead and removing latency.
Direct-to-display for intuitively attaching VR headsets, to deliver a seamless plug-and-play virtual reality experience from an AMD Radeon™ graphics card to a connected VR headset, while enabling features such as booting directly to the display or using extended display features within Windows.

What’s next for LiquidVR?
It all depends on what you were expecting, and what the rest of the industry does. AMD hopes LiquidVR will be compatible with a broad range of VR devices. LiquidVR will allow hardware makers to implement AMD technology in their products with relative ease, enabling 100Hz refresh rates, the use of individual GPUs per each eye and so on.
To a certain extent, you can think of LiquidVR as FreeSync for VR kit.
Oculus CEO Brendan Irbe said achieving presence in a virtual world is one of the most important elements needed to deliver a good user experience.
He explained where AMD comes in:
“We’re excited to have AMD working with us on their part of the latency equation, introducing support for new features like asynchronous timewarp and late latching, and compatibility improvements that ensure that Oculus’ users have a great experience on AMD hardware.”
Raja Koduri, corporate vice president, Visual Computing, AMD, said content, comfort and compatibility are the cornerstones of AMD’s focus on VR.
AMD’s resident graphics guru said:
“With LiquidVR we’re collaborating with the ecosystem to unlock solutions to some of the toughest challenges in VR and giving the keys to developers of VR content so that they can bring exceptional new experiences to life.”
A picture is worth a thousand words, so here’s 3300 frames of AMD’s virtual reality vision.
Can MediaTek Take On Qualcomm?
While Qualcomm’s 20nm Snapdragon 810 SoC might be the star of upcoming flagship smartphones, it appears that MediaTek has its own horse for the race, the octa-core MT6795.
Spotted by GforGames site, in a GeekBench test results and running inside an unknown smartphone, MediaTek’s MT6795 managed to score 886 points in the single-core test and 4536 points in the multi-core test. These results were enough to put it neck to neck with the mighty Qualcomm Snapdragon 810 SoC tested in the LG G Flex 2, which scored 1144 points in the single-core and 4345 in the multi-core test. While it did outrun the MT6795 in the single-core test, the multi-core test was clearly not kind on the Snapdragon 810.
The unknown device was running on Android Lollipop OS and packed 3GB of RAM, which might gave the MT6795 an edge over the LG G Flex 2.
MediaTek’s octa-core MT6795 was announced last year and while we are yet to see some of the first design wins, recent rumors suggested that it could be powering Meizu’s MX5, HTC’s Desire A55 and some other high-end smartphones. The MediaTek MT6795 is a 64-bit octa-core SoC clocked at up to 2.2GHz, with four Cortex-A57 cores and four Cortex-A53 cores. It packs PowerVR G6200 graphics, supports LPDDR3 memory and can handle 2K displays at up to 120Hz.
As we are just a few days from Mobile World Congress (MWC) 2015 which will kick off in Barcelona on March 2nd, we are quite sure that we will see more info as well as more benchmarks as a single benchmark running on an unknown smartphone might not be the best representation of performance, it does show that MediaTek certainly has a good chip and can compete with Qualcomm and Samsung.
Microsoft Cuts The Darkside

Comments Off on Microsoft Cuts The Darkside
The security of the employees of Phantom Dust developer Darkside Game Studios is in doubt, after Microsoft decided to sever all professional ties to the studio.
Phantom Dust is a remake of an Xbox game from 2004, which was designed by Yukio Futatsugi, the creator of Panzer Dragoon. Darkside’s project was unveiled at E3 last year as an exclusive title for the Xbox One, but whatever agreement existed between the studio and Microsoft has been terminated.
Here’s the official line: “Microsoft partnered with Darkside Game Studios in the development of Phantom Dust, but our working relationship has now ended. We have great respect for their studio and their work in the industry.
“While we do not have anything new to share on Phantom Dust at this time, we can confirm that development of the title continues. We look forward to sharing more details on the game as we get closer to release.”
Darkside, which is based in Florida, has contributed to the development of a host of major releases, including a couple of Xbox exclusives: Sunset Overdrive, Gears of War: Judgment, the Borderlands franchise, the Bioshock franchise; it’s a solid track record, albeit entirely composed of contract work, and Phantom Dust was to be its first solo project.
However, the “respect” Microsoft has for that track record is now the subject of suspicion, with several sources from within Darkside claiming that the company has been forced to layoff its entire staff – around 50 people.
“The executives who saw it were impressed and as late as this morning gave our team every indication that the project was on solid ground,” one of the sources said to Kotaku. “Yet we got the phone call today that someone up on high who in all likelihood wasn’t even aware of the game in detail shut it down.”
The notion that the alleged termination of Darkside’s working relationship with Microsoft was sudden is reinforced by the studio’s recruitment page, which advertised six open positions as recently as the start of January. Among the perks listed there, one stands out: “Working with major publishers.”
Microsoft offered no comment on the situation at Darkside, but we are pursuing the studio’s management for clarification.
Intel Gives Exascale A Boost
Intel’s exascale computing efforts have received a boost with the extension of the company’s research collaboration with the Barcelona Supercomputing Center.
Begun in 2011 and now extended to September 2017, the Intel-BSC work is currently looking at scalability issues with parallel applications.
Karl Solchenbach, Intel’s director, Innovation Pathfinding Architecture Group in Europe said it was important to improve scalability of threaded applications on many core nodes through the OmpSs programming model.
The collaboration has developed a methodology to measure these effects separately. “An automatic tool not only provides a detailed analysis of performance inhibitors, but also it allows a projection to a higher number of nodes,” says Solchenbach.
BSC has been making HPC tools and given Intel an instrumentation package (Extrae), a performance data browser (Paraver), and a simulator (Dimemas) to play with.
Charlie Wuischpard, VP & GM High Performance Computing at Intel said that the Barcelona work is pretty big scale for Chipzilla.
“A major part of what we’re proposing going forward is work on many core architecture. Our roadmap is to continue to add more and more cores all the time.”
“Our Knights Landing product that is coming out will have 60 or more cores running at a slightly slower clock speed but give you vastly better performance,” he said.
MediaTek Shows Off New IoT Platform
Comments Off on MediaTek Shows Off New IoT Platform
MediaTek had announced a new development platform, as part of its MediaTek Labs initiative.
The LinkIt Connect MT7681 platform is based on the MT7681 SoC, designed for simple and affordable WiFi-enabled Internet of Things (IoT) devices. The company also released a software development kit (SDK) and hardware development kit (HDK) for the new platform.
The HDK includes the LinkIt Connect 7681 development board, which features the MT7681 chipset, micro-USB port and pins for various I/O interfaces. The chipset can be used in WiFi station or access point modes.
In station mode, the chip connects to a wireless access point and communicates with web services or cloud servers, which means it could be used to control smart thermostats. However, in access point mode, the chipset can communicate with devices directly, for example to control smart plugs or light bulbs using a smartphone.
“The world is rapidly moving towards connecting every imaginable device in the home, yet developers often have to spend too much effort on making their products Wi-Fi enabled,” said Marc Naddell, VP, MediaTek Labs. “The MediaTek LinkIt Connect 7681 platform simplifies and accelerates this process so that developers can focus on making innovative home IoT products, whatever their skill level.”
MediaTek Labs was launched in September 2014 and its goal is to promote a range of innovative MediaTek platforms, namely frugal devices such as wearables, IoT and home automation hardware.
Dell Debuts Ubuntu Based Mobile Workstation
Comments Off on Dell Debuts Ubuntu Based Mobile Workstation
Dell has unleashed a mobile workstation aimed at developers, designed to be the “beast” to the already available XPS 13 ultra-mobile system “beauty”.
The Precision M3800 was previously available only with Microsoft Windows 8.1, but the new Precision M3800 Developer Edition will ship with the Ubuntu 14.04 Long Term Support Linux distro.
The developer version was unveiled by Barton George, Dell’s director of developer programmes, who talked about the company’s “beauty and the beast” strategy for Linux-powered PCs to produce an ultra-portable laptop as the XPS 13 and then a more capable machine.
Work on making the Precision M3800 a more Ubuntu-friendly machine started soon after the XPS 13 release thanks to developer Jared Dominguez, who improved the code in his personal time and put together instructions on how to run the OS on the machine.
After listening to “tremendously positive” feedback, George said that Dell has now officially added a Ubuntu 14.04 LTS customisation option to the company’s official online shop.
The Precision M3800 Developer Edition weighs 1.88kg, and is less than 18mm thick. It runs a 4th-generation Intel Core i7 quad-core CPU coupled with an Nvidia Quadro K1100M GPU, 16GB of RAM and a 4K Ultra HD screen option.
Dominguez explained that there are still problems with Ubuntu support for the Precision M3800 hardware as the distro shipped with the first M3800 units doesn’t include support for Thunderbolt ports.
The updated kernel of Ubuntu 14.04.2 will add “some” Thunderbolt support, however, thanks to the hardware-enablement stack in Ubuntu, the developer said.
Microsoft Unveils Hologram Visor

Comments Off on Microsoft Unveils Hologram Visor
Microsoft Corp surprised the tech world with the unveiling of a prototype hologram visor that can bring the Minecraft video game, Skype calls and even the landscape of Mars to three-dimensional life.
The veteran tech pioneer, which long ago lost the mantle of the world’s most inventive company, is making a bold play to regain that title in the face of stiff competition from Google Inc and Apple Inc.
Virtual or enhanced reality is the next frontier in computing interaction, with Facebook Inc focusing on its Oculus virtual reality headset and Google working on its Glass project.
Microsoft said its wire-free Microsoft HoloLens device will be available around the same time as Windows 10 this autumn. Industry analysts were broadly excited at the prospect, but skeptical that it could produce a working model at a mass-market price that soon.
“That was kind of a ‘Oh wow!’ moment,” said Mike Silver, an analyst at Gartner who tried out the prototype on Wednesday. “You would expect to see a relatively high-priced model this year or next year, then maybe it’ll take another couple of years to bring it down to a more affordable level.”
Microsoft does not have a stellar record of bringing ground-breaking technology to life. Its Kinect motion-sensing game device caused an initial stir but never gripped the popular imagination.
The company showed off a crude test version of the visor – essentially jerry-rigged wires and cameras pulled over the head – to reporters and industry analysts at a gathering at its headquarters near Seattle.
It did not allow any photographs or video of the experience, but put some images on its website.
Is Qualcomm Overheating?
South Korean smartphone maker LG Electronics Inc said on Thursday that it has not experienced any overheating problems with Qualcomm Inc’s new Snapdragon processor that is powering a curved-screen device going on sale later this month.
“I am very much aware of the various concerns in the market about the (Snapdragon) 810, but the chip’s performance is quite satisfactory,” Woo Ram-chan, LG vice president for mobile product planning, told reporters at a press event for the company’s G Flex2 smartphone.
The comment came after Bloomberg reported a day earlier that Samsung Electronics Co Ltd, the world’s top smartphone maker, decided not to use the new Qualcomm processor for the next flagship Galaxy S smartphone after the chip overheated during testing. Samsung and Qualcomm have declined to comment on the report, which cited unidentified sources.
Samsung is widely expected to unveil the new Galaxy S smartphone in early March, and Bloomberg reported that the Korean firm will use its own processors instead.
But LG’s Woo said on Thursday that internal tests for the G Flex2, powered by the new Qualcomm processor, show that the new product emits less heat than other existing devices. The new phone is scheduled to start selling in South Korea on Jan. 30.
“I don’t understand why there is a issue over heat,” he said.
AMD Headed To The Facial Recognition Space
Comments Off on AMD Headed To The Facial Recognition Space
AMD has developed facial recognition technology to enable users to organize and search video clips based on the people featured in them.
AMD executive Richard Gayle demonstrated to Tom’s Guide how AMD Content Manager, uses facial recognition to browse through a group of local videos to find specific faces.
There is an index that displays the people’s faces that have been detected throughout the video clips.
The user can edit the names of the people as well as add keyword tags to help improve future searches for specific people.
For instance, if you are searching for videos that feature one person, you can click on his or her respective face to pull up the corresponding videos.
Additionally, if you want to narrow a search to a specific person combined with a keyword tag, you can drag the face icon and click on the desired keyword.
Once you click on the video you wish to view, a player appears in the right windowpane, along with a timeline displayed at the bottom with a list of all the people who appear in the video.
The timeline is separated into various coloured boxes to mark the exact moment in the video when each person first appears on screen, so you do not have to watch the entire video to see the bit you want.
The application also has facial recognition capabilities that allow users to do some basic editing, such as compiling a single montage video of any individual or individuals.
While this is pretty good technology, it probably does not have any major use yet on its own.
Gayle said it is unlikely that AMD will release Content Manager in its current form but will license it to OEMs that are able to rebrand the application before offering it on their respective systems.
He claimed that only AMD processors have sufficient power to operate the application, because of the processor’s ability to have the CPU, GPU and memory controller work closely together.
AMD’s Fiji GPU Goes High Bandwidth
New evidence coming from two LinkedIn profiles of AMD employees suggest that AMD’s upcoming Radeon R9 380X graphics card which is expected to be based on the Fiji GPU will actually use High-Bandwidth Memory.
Spotted by a member of 3D Center forums, the two LinkedIn profiles mention both the R9 380X by name as well as describe it as the world’s firts 300W 2.5D discrete GPU SoC using stacked die High-Bandwidth Memory and silicon interposer. While the source of the leak is quite strange, these are more reliable than just rumors.
The first in line is the profile of Ilana Shternshain, an ASIC Physical Design Engineer, which has been behind the Playstation 4 SoC, Radeon R9 290X and R9 380X, which is described as the “largest in ‘King of the hill’ line of products.”
The second LinkedIn profile is the one from AMD’s System Architect Manager, Linglan Zhang, which was involved in developing “the world’s first 300W 2.5D discrete GPU SOC using stacked die High Bandwidth Memory and silicon interposer.”
Earlier rumors suggest that AMD might launch the new graphics cards early this year as the company is under heavy pressure from Nvidia’s recently released, as well as the upcoming, Maxwell-based graphics cards.
